11. The anchor has slanted pallets on the arms which alternately catch on the teeth of the escape wheel , receiving impulses. 12. As the powered escape wheel rotates clockwise, the entrance tooth slides across the sloping impulse plane of the entrance pallet. 13. This turns the pallets about their axis, which places the exit pallet into the path of the rotating escape wheel . 14. There are actually two escape wheels mounted on the same shaft and two surfaces on each of the two pallet pins. 15. For example, the driven escape wheels are smaller than the drivers and a sprung setting for the detent is introduced. 16. Instead of using teeth, the escape wheel has round pins that are stopped and released by a scissors-like anchor. 17. An impulse from the escape wheel to the impulse roller is nearly dead-beat, meaning little sliding action needing lubrication. 18. Chronometer escape wheels and passing springs are typically gold due to the metal's lower slide friction over brass and steel. 19. Despite being locked at rest most of the time, the escape wheel rotates typically at an average of 10 rpm or more. 20. This means that the pin holds the stop which holds the pallet in just the right place to engage cleanly with the escape wheel .
